LINE-CASTING MACHINE.

To all whom it may concern:

Be it known that I, CARL M'UnnLnIsnN, a citizen of the United States ofAmerica, residing at 88 Chausseestrasse, Berlin, N. a, in the-Empire ofGermany, have invented new and useful Improvements in Line- CastingMachines, of which the following is a specification.

The present invention consists of improvements in the line-castingmachines described in the specification of Letters Patent No. 436,532.

The accompanying figure is a side elevation of the preferredconstructional form of this invention.

73 is the cam shaft; 74, a cam fast on it; 76, a bell-crank cam lever;77, the first elevator, whose function is to receive the composed lineof matrices 78 and lower them to the mold, the said elevator risingafter the casting operation in order to deliver the composed line to thedistributor. The parts 73, 77 and 78 are as in the above-named patent,in which, however, the weight of the elevator 77 rested upon a springcontained within a vertical tube carried by the front end of the camlever 76. According to the present invention, the first elevator 77 issuspended from the cam lever 7 6 by a stud 80 projecting from the saidelevator; a link 81 having a vertical slot 82 in its upper end and inwhich the stud 80 engages, and having a similar slot 83 in its lower endand in which engages a stud 84 fast on the front end of the cam lever76. The spring 85 is connected at its upper end with the upper end oflink 81 and at its lower end with the lower end of the elevator frame,and is under such tension that the elevator frame will normally besustained by the spring and drawn up with the pin 80 in the upper end ofthe slot 82.

86 is a set screw extending downwardly through the lower end of the link81 and into the upper end of the slot 83 in position to be engaged bythe stud 84, by which means the amount of play or lost motion betweenthe arm 76 and the link 81 may be varied.

When repeat type bars are to be cast from the same composed line, theelevator 77 must not be raised as high toward the distributer after acast when that line is in two faces as when it is in a single face; for

if it were, the variant face matrices (which stand higher in thecomposed line than those of the normal face) would be depressed to thelevel of the latter by contact with the well known depressor as theelevator was attaining the highest point in its rise. The selection ofheight to which the elevator 77 may rise, is made by a detent which ismoved into the path of the rising elevator if the line is in two faces,and kept out of that path if the line is in a single face. Both theoperation of casting repeat type bars and the construction andarrangement of the detent are well known in the art and therefore do notrequire further description. Now the rise of the lever 7 6 and,therefore, that of the link 81 is constant.

When the detent is adjusted in the path of the rising elevator so as toarrest the same, the cam lever 76 will be permitted to complete its fullstroke, the slot 82 in the link 81 permitting the link to move upwardlyrelative to the arrested elevator, and the spring yielding in thisrelative motion. When however, the detent is adjusted free of the pathof the rising elevator so that the same will be permit-ted to move toits full extent, the complete stroke of the cam lever will result in thepositive rise of link 81 as before, and this motion will be transmittedto the elevator through the medium of the spring 85, which suspends theeleyatlor and carries the same along with the in z.

Having described my invention I declare that what I claim and desire tosecure by Letters Patent is 1. In a line casting machine, thecombination of an actuating lever, a rising and falling elevator, a linkconnected with the lever and having a limited sliding connection withthe elevator, and a tension spring connected with the link and with theelevator and acting by its pull to yieldingly suspend the elevator;whereby if the ascent of the elevator is arrested, the link will bepermitted by the stretch of the spring to continue its motion relativeto the elevator.

2. In a line casting machine, the combination of an actuating lever, arising and falling elevator, a link connected with the lever and havinga limited sliding connection with the elevator, and a tension springconnected withthe link and connected also with the elevator at a pointbelow the connection of the link with the elevator.

3. In a line casting machine, the com bination of an actuating lever,,alink mov' able with the lever and also relatively thereto, a rising andfalling elevator movable with said link and also relatively thereto, anda spring cooperating with the elevator and link to yieldingly supportthe elevator on the link.

4. In a line casting machine, the com-' which the link is adapted tomove upwardly to a limited extent, and a spring cooperating with thelink and elevator to: yieldingly resist their movements relative to eachother.

.5. In a line casting machine, the combination of an actuating levermovable up and down, a link correspondingly movable I with the lever andin relation to which link the lever is adapted to move downwardly to alimited extent, an elevator movable up and down with the link and inrelation to 1 which the link is adapted to move upwardly to a limitedextent, and a yieldingconnection between the link and elevator.

In witness whereof I have hereunto set my hand in the presence of twowitnesses.v
